Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a pressure cooking utensil. BACKGROUND

[0002] After completing pressure cooking, the pressure cooking utensil needs to be depressurized to balance the air pressure in the pot with the outside atmosphere, so that the pot can be safely opened. The traditional pressure cooking utensil is depressurized by exhaust, which is not only slow in depressurization speed, but also accompanied by loud noise during the depressurization process, and the liquid in the pot is also sprayed out during the exhaust process, causing the pot cover to be contaminated and affecting the user experience.

[0003] In order to improve the depressurization efficiency, some pressure cooking utensils use water cooling to depressurize. Compared with exhaust depressurization, water cooling depressurization is faster and generates less noise during the depressurization process, so it is increasingly applied to pressure cooking utensils.

[0004] The cooking utensil using water cooling to depressurize is provided with a water tank on the pot cover or the pot body, and a cooling cavity is arranged on the pot cover. After the pressure cooking is completed, the cooling liquid in the water tank flows into the cooling cavity to cool the air in the pot, and the cooled cooling liquid flows back to the water tank, so that the cooling liquid circulates. However, after the cooling liquid exchanges heat with the high-temperature air, the temperature of the cooling liquid rises, which results in a higher cooling efficiency of the cooling liquid during the first circulation between the water tank and the cooling cavity, and as the temperature of the cooling liquid rises, the temperature difference between the cooling liquid and the air in the pot becomes smaller, which gradually reduces the efficiency of water cooling. This results in a long water cooling depressurization process, and the overall depressurization speed and efficiency are difficult to improve, which leads to a poor user experience. SUMMARY

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0045] As shown in Figure 2 , Figure 3 , a pressure cooking utensil includes a pot body 1 and a pot cover 2, the pot cover 2 is provided with a cooling cavity 211, the pressure cooking utensil further includes a water tank 3 arranged on the pot body 1 or the pot cover 2, the water tank 3 is communicated with the cooling cavity 211 to supply cooling liquid into the cooling cavity 211, and the pressure cooking utensil further comprises a cooling member arranged inside the pressure cooking utensil, the cooling member is used for cooling the cooling liquid in the water tank 3.

[0046] In the present application, the water tank 3 is communicated with the cooling cavity 211 on the pot cover 2, and then the water cooling mode is used to reduce the pressure after the pressure cooking is completed, so as to realize the exhaust-free pressure reduction. Compared with the exhaust pressure reduction mode, the pressure reduction time can be shortened, the user can open the cover earlier, and the noise generated in the exhaust process is avoided, and the use experience is improved.

[0047] In addition, the pressure cooking utensil of the present application further comprises a cooling member, which is used for cooling the cooling liquid in the water tank 3, so that the cooling liquid always maintains a relatively low temperature during the whole water cooling pressure reduction process. In the multiple circulation flows of the cooling liquid between the water tank 3 and the cooling cavity 211, the cooling liquid always maintains a relatively large temperature difference with the high-temperature gas in the pot, so as to maintain a relatively high heat exchange efficiency, greatly improve the water cooling efficiency, and shorten the water cooling pressure reduction time.

[0048] It should be noted that the present application does not limit the cooling method of the cooling member for the cooling liquid. In one embodiment, the cooling member is located inside the water tank 3 to directly contact the cooling liquid in the water tank 3, and then directly cools the cooling liquid. In another embodiment, the cooling member is located outside the water tank 3 to cool the water tank 3 first, and then cool the cooling liquid inside the water tank 3 through the tank wall of the water tank 3.

[0049] The present application does not limit the type of cooling member, which includes but is not limited to the following embodiments:

[0050] Embodiment one: in the present embodiment, as shown inFigures 2 to 4 As shown, the cooling member comprises a cooling fan 4, which is capable of blowing cold air to the water tank 3 to cool the cooling liquid in the water tank 3.

[0051] The cooling fan 4 blows cold air to the water tank 3 to cool the cooling liquid in the water tank 3 in a way of air cooling, which ensures the cooling effect of the cooling liquid and enables the cooling fan 4 to be designed in a separate structure from the water tank 3. Thus, the cooling fan 4 can be fixed inside the pressure cooking appliance, and the water tank 3 can be designed in a detachable structure to be taken out for water refilling. After the water tank 3 is installed, the cooling fan 4 can still cool the water tank 3 by air flow. In addition, the cooling of the cooling liquid in the water tank 3 by air flow can also be designed to cool other components in the pressure cooking appliance by air flow at the same time, so as to realize multiple purposes of the cooling fan 4, save cost, and achieve one thing with multiple purposes.

[0052] It should be noted that, in a preferred embodiment, the water tank 3 is a closed structure and is only communicated with the cooling cavity 211 through the communication port. When the cooling fan 4 works, it blows cold air towards the tank wall of the water tank 3 to cool the cooling liquid in the water tank 3 through the tank wall. At the same time, the cooling liquid in the water tank 3 is prevented from spilling out of the water tank 3. In other embodiments, the water tank 3 can also be designed as an open structure, so that the cold air blown by the cooling fan 4 can directly contact the cooling liquid in the water tank 3 to cool it.

[0053] Further, as shown in Figure 4 The cooling fan 4 has an air outlet, and the water tank 3 is provided with a windward wall 31 corresponding to the air outlet.

[0054] The windward wall 31 is provided to enable the air flow blown by the cooling fan 4 to collide with the windward wall 31 and then flow along the surface of the windward wall 31, which helps to increase the contact time of the cold air with the water tank 3 and improve the heat exchange efficiency.

[0055] Preferably, the windward wall 31 has a wind guide surface, and the air flow blown by the cooling fan 4 flows to at least one of the top wall, the side wall or the bottom wall of the water tank 3 through the guidance of the wind guide surface. After the cold air blown to the windward wall 31 contacts the wind guide surface, it is guided by the wind guide surface to flow to other sides of the water tank 3, thereby forming a surrounding manner to the water tank 3, which further increases the contact area of the cold air with the water tank 3 and improves the cooling effect.

[0056] Specifically, the wind guide surface can be a slope extending in a direction towards at least one of the top wall, the side wall or the bottom wall of the water tank 3, or a circular arc surface, and of course, the wind guide surface can also be a spherical surface to uniformly disperse the air flow to each side of the water tank 3.

[0057] Further, as shown in Figure 4As shown, the windward wall 31 is provided with a heat dissipation rib 311. The heat dissipation rib 311 is protruded on the outer side of the windward wall 31.

[0058] The heat dissipation rib 311 increases the surface area of the windward wall 31, which on one hand further increases the contact area between the cold air and the windward wall 31, thereby improving the air cooling effect, and on the other hand is more conducive to the heat dissipation of the water tank 3 itself. Through the above two ways of heat dissipation and cooling, the temperature of the water tank 3 and the cooling liquid inside it can be quickly reduced.

[0059] Specifically, as shown in the drawings, Figure 4 The heat dissipation rib 311 is a plurality of heat dissipation ribs, which can be arranged in an array on the windward wall 31, or can be arranged in other ways, for example, using a plurality of heat dissipation ribs 311 to build a logo, pattern, etc., to improve the appearance of the water tank 3.

[0060] The present embodiment does not limit the position of the cooling fan 4, and preferably, as shown in the drawings, Figure 3 , Figure 4 The cooling fan 4 has an air outlet, and the cooling fan 4 is arranged adjacent to the water tank 3, and the air outlet faces the water tank 3.

[0061] The cooling fan 4 is arranged adjacent to the water tank 3, so that the length of the air duct between them is short, and then the cold air can quickly flow to the water tank 3, improving the air cooling efficiency.

[0062] In another embodiment, the cooling fan 4 can also be arranged at any position of the pressure cooking appliance, without being limited by the position of the water tank 3. It is only necessary to set up an air duct to guide the cold air blown by the cooling fan 4 to the water tank 3. Specifically, the cooling fan 4 and the water tank 3 can be both arranged on the pot body 1, or both arranged on the pot cover 2. Alternatively, one of the cooling fan 4 and the water tank 3 is arranged on the pot body 1, and the other is arranged on the pot cover 2, which is not limited here.

[0063] Preferably, as shown in the drawings, Figures 2 to 4 The pressure cooking appliance further comprises an air flow channel 6, the air flow channel 6 has an air inlet end 62 and an air outlet end 63, the air inlet end 62 is connected in communication with the air outlet of the cooling fan 4, and the air outlet end 63 faces the water tank 3. The air outlet end 63 is provided with an outwardly expanding and extending flared section 61.

[0064] The air outlet end 63 of the air flow channel 6 is provided with the flared section 61, so that the cold air diffuses and flows out of the air flow channel 6. On one hand, it can increase the contact area between the cold air and the water tank 3 and the cooling liquid inside the water tank 3, and improve the cooling effect. On the other hand, the flared section 61 can slightly reduce the flow rate and kinetic energy of the cold air when blowing to the water tank 3, thereby making the contact between the cold air and the cooling liquid more gentle. On the basis of ensuring the cooling effect, it avoids the cold air disturbing the cooling liquid in the water tank 3 to roll violently, and reduces the risk of the cooling liquid spilling out of the water tank 3.

[0065] It should be noted that the air flow passage 6 in the embodiment can be provided regardless of the arrangement of the cooling fan 4 and the water tank 3. For example, the cooling fan 4 and the water tank 3 can be arranged adjacent to each other, and a short air flow passage 6 can be provided therebetween. When the cooling fan 4 and the water tank 3 are far away from each other, a long air flow passage 6 can be provided.

[0066] In a preferred embodiment, as shown in Figures 2 to 4 , the water tank 3 is arranged in the pot body 1, and the cooling fan 4 is also arranged in the pot body 1. Meanwhile, the pot body 1 is also provided with a water pump 5, which is in communication with the water tank 3, and is used to pump the cooling liquid in the water tank 3 into the cooling cavity 211 of the pot cover 2. Specifically, as shown in Figure 4 , the pot body 1 includes an outer cover and a base arranged below the outer cover, and the water pump 5, the water tank 3 and the cooling fan 4 are arranged in the base. Of course, as shown in Figure 6 , the water tank 3 and the water pump 5 can also be arranged in the pot cover 2.

[0067] Specifically, as shown in Figure 4 , Figure 5 , the cooling fan 4 is fixed to the bottom of the pot body 1, and the bottom wall of the pot body 1 is provided with an air inlet 11 in communication with the cooling fan 4. The air inlet 11 is arranged in the bottom wall of the pot body 1, and when the pressure cooking appliance is placed on the countertop, the user cannot see the air inlet 11, thereby achieving a hidden design, ensuring the uniformity of the appearance of the pot body 1, improving the appearance quality, and avoiding external impurities from entering the interior of the pot body 1 through the air inlet 11.

[0068] Further, the pot body 1 is internally provided with a circuit board, the pot body 1 has a first mounting area for mounting the water tank 3 and a second mounting area for mounting the circuit board, and the pressure cooking appliance is internally provided with a first cooling air duct and a second cooling air duct, the first cooling air duct being in communication with the cooling fan 4 and the first mounting area, and the second cooling air duct being in communication with the cooling fan 4 and the second mounting area.

[0069] Part of the cold air blown by the cooling fan 4 is guided to the first mounting area through the first cooling air duct and blown to the water tank 3, thereby cooling the water tank 3 and the cooling liquid in the water tank 3. Another part of the cold air is guided to the second mounting area through the second cooling air duct and blown to the circuit board, thereby cooling the circuit board. Thus, the cooling fan 4 realizes the integration of the functions of air cooling of the cooling liquid and air cooling of the circuit board, one thing with multiple uses, simplifies the internal structure of the pressure cooking appliance, and saves costs.

[0070] Of course, the cooling fan 4 can also be used for other purposes, for example, part of the cold air blown by the cooling fan 4 is blown to the inner liner to assist in cooling the cooking cavity, so that the pressure cooking appliance realizes dual cooling of water cooling and air cooling, and further improves the pressure reduction efficiency.

[0071] In this embodiment, the cooling member comprises a refrigeration member, which is electrically connected with the control unit of the pressure cooking appliance, and is arranged inside or outside the water tank 3 to cool the cooling liquid in the water tank 3.

[0072] The refrigeration member is electrically connected with the control unit to be started to refrigerate under the program control of the pressure cooking appliance, and the refrigeration member generates less noise and has higher refrigeration efficiency when working than the fan refrigeration.

[0073] The refrigeration member can be fixed inside the water tank 3 to directly contact with the cooling liquid to cool it, or can be fixed outside the water tank 3 to cool the cooling liquid through the tank wall of the water tank 3.

[0074] Preferably, as shown in Figure 2 , Figure 3 , the water tank 3 is detachably mounted on the pot body 1 or the pot cover 2, and the cooling member is in a split structure with the water tank 3.

[0075] The water tank 3 is in a detachable structure to facilitate the user to supplement the cooling liquid in the water tank 3, and the cooling member is split with the water tank 3, so that the cooling member is not detached together with the water tank 3 after the water tank 3 is detached, but is always fixed inside the pressure cooking appliance. Since the cooling member is connected with wires, air ducts and other structures, the position is fixed, so that the connection of the air duct, circuit and the like is more stable, and the reliable working of the cooling member is ensured.

[0076] For the embodiment in which the cooling member is the cooling fan 4, the water tank 3 is arranged at the cooling fan 4 or the air outlet of the air flow channel 6 when the water tank 3 is mounted on the pressure cooking appliance. For the embodiment in which the cooling member is the refrigeration member, the water tank 3 is arranged to contact with the outer tank wall of the water tank 3 after the water tank 3 is mounted on the pressure cooking appliance.

[0077] Preferably, as shown in Figure 1 , Figure 2 , Figure 3 , the outer surface of the water tank 3 is flush with the outer surface of the pot cover 2 or the pot body 1.

[0078] It can be understood that the outer surface of the water tank 3 is flush with the outer surface of the pot body 1 when the water tank 3 is mounted on the pot body 1, and the outer surface of the water tank 3 is flush with the outer surface of the pot cover 2 when the water tank 3 is mounted on the pot cover 2.

[0079] After the water tank 3 is installed in the installation groove 12, the outer surface is flush with the outer surface of the pressure cooking utensil, which not only realizes the exposed design of the local area of the water tank 3, but also enables the user to directly see the cooling liquid remaining amount in the water tank 3, facilitates the user to timely supplement the cooling liquid in the water tank 3, and makes the water tank 3 not excessively protrude from the outer surface of the pressure cooking utensil, so that the appearance of the pressure cooking utensil is more uniform and beautiful, and the appearance quality and texture are improved. Meanwhile, the partial exposure of the water tank 3 also facilitates the user to assemble and disassemble, and the operation is more convenient.

[0080] Preferably, the outer surface of the water tank 3 is provided with a handle position, so as to facilitate the user to take the water tank 3 off the pressure cooking utensil.

[0081] Specifically, as shown in Figures 1 to 5 the water tank 3 is arranged on the pot body 1 and located at the bottom of the side wall of the pot body 1, the water tank 3 is inserted into the installation groove 12 from one side of the pot body 1 in a transverse direction, and the installation groove 12 extends to the bottom of the pot body 1, so that the lower surface of the water tank 3 is exposed, and the user can take the water tank 3 out of the installation groove 12 by gripping the bottom of the water tank 3.

[0082] In other embodiments, the water tank 3 can also be arranged on the pot cover 2. Specifically, as shown in Figure 6 the installation groove 12 is arranged on the top wall of the pot cover 2 and extends to the side of the pot cover 2, so that after the water tank 3 is installed, the side surface of the upper surface of the water tank 3 is exposed, facilitating the user to take out.

[0083] It should be noted that the forming mode of the cooling cavity 211 is not limited in the utility model, which can be one of the following embodiments:

[0084] Embodiment one: in this embodiment, the pot cover 2 includes a cover body 22, an inner cover 23 and a cooperating piece, the cooperating piece cooperates with the inner cover 23 to form the cooling cavity 211.

[0085] In one embodiment, the cooling cavity 211 is located inside the cooperating piece, the cooperating piece is fixedly connected with the inner cover 23 and in contact with the upper surface of the inner cover 23, when water cooling, the cooling liquid enters the inside of the cooling cavity 211, so that the temperature of the cooperating piece is reduced, then the cooperating piece cools the inner cover 23 through contact, and further cools and depressurizes the cooking cavity below the inner cover 23.

[0086] In another embodiment, the cooperating piece is fixed on the upper side or the lower side of the inner cover 23, so that the cooling cavity 211 is located between the inner cover 23 and the cooperating piece. When the cooperating piece is located on the upper side of the inner cover 23, the cooling liquid directly contacts the inner cover 23 to cool the inner cover 23, and further reduce the temperature in the cooking cavity below the inner cover 23. When the cooperating piece is located on the lower side of the inner cover 23, the air in the cooking cavity can directly contact the cooperating piece, so as to achieve the effect of cooling and reducing temperature.

[0087] Embodiment two: in this embodiment, as shown in Figure 6 The pot cover 2 includes a cover body 22 and an inner cover 23, the cover body 22 is provided with a water cooling piece 21, the water cooling piece 21 penetrates the inner cover 23 to extend into the inside of the pot body 1, and a cooling cavity 211 is located in the inside of the water cooling piece 21.

[0088] The water cooling piece 21 is arranged on the cover body 22, the cooling cavity 211 is located in the inside of the water cooling piece 21, and the lower end of the water cooling piece 21 penetrates the inner cover 23 to extend into the pot body 1 to directly contact with high-temperature gas in the cooking cavity, so that the cooking cavity is cooled, and the purpose of rapid pressure relief is achieved. Since the water cooling piece 21 is arranged on the cover body 22, even if the inner cover 23 is a structure capable of rotating relative to the cover body 22, the cover body 22 will not move, thereby ensuring that the water cooling piece 21 and the water cooling pipeline connected with the water cooling piece 21 will not change position, thereby maintaining stable connection and sealing of the water cooling pipeline and the cooling cavity 211, and improving the reliability of pipeline connection.

[0089] In addition, if the inner cover 23 is a structure capable of being detached from the cover body 22, the water cooling piece 21 is always kept on the cover body 22 and will not change position with the mounting and dismounting of the inner cover 23, thereby on the one hand, the user does not need to connect and install the water cooling pipeline with the cooling cavity 211 when mounting the inner cover 23, reducing the mounting and dismounting efficiency and operation convenience of the inner cover 23 and improving the use experience. On the other hand, the water cooling pipeline can always be connected with the cooling cavity 211, without the need to frequently connect the water cooling pipeline and the cooling cavity 211, thereby ensuring the connection sealing, further reducing the risk of water cooling liquid leakage, and ensuring the water cooling efficiency.
